Add Rabbit to the list of characters in Marshall Mathers' rapping repertoire.

With four new tracks on the "8 Mile" soundtrack — one featuring Obie Trice and 50 Cent — the voice behind Eminem and Slim Shady has found another set of life stories to tell.

"The '8 Mile' soundtrack was different because it forced me to step into Rabbit, the character I play in the film, and write from his point of view," Eminem said in a statement. "It was a challenge."

Eminem spent last week in Detroit shooting the video for "Lose Yourself," the first single from the soundtrack, due October 29. Phillip Atwell, who has co-directed several of Slim's videos, and the rapper's manager, Paul Rosenberg, co-directed the clip, which will blend performance shots with scenes from the movie.
